Abstract

The results of neutron diffraction investigations on TbMn2D2, TbMn2D3 and ErMn2D2 are presented and analysed. The magnetic ordering temperatures of TbMn2Dx are 284 and 299 K for x=2 and 3, respectively. Their magnetic structures are antiferromagnetic and collinear with the propagation vector Image. The ErMn2D2 orders magnetically at about 214 K. The differentiated temperature behaviour of Mn and rare earth (Tb and Er) magnetic sublattices is observed. The magnetic moments of Mn and rare earths have different temperature dependence.
